Formula -- good point as well. I may expose a portion of the ATF fins in the rad block to prevent abnormal heat.

I'm wondering if there's a quick way to monitor ATF temps -- like a sensor on the dipstick or something...

If this works, it will solve a long-time issue of cable adjustment mishaps and ECUs working against me

To monitor ATF temps, you can get any oil-temp gauge, and install the probe through the pan with sealant. They usually screw in, and you can just put a rubber washer on either side with a nut on the inside to keep it from leaking.

That will give you pan temps, which are the best temps to read.
